most, if not all lenses don't work in AF for shooting dark sky images, and many in my experience require some fiddling and experimenting to get proper focus, most do not get critical focus at infinity. I have rented two different Sigma 20Art lenses, and both of them were a bit different for what was critical. My Batis 18 is pretty easy with the OLED, you can see it at night and after using the SharpStar to help, I know what point is perfect focus for stars.

I use the Rokinon 14mm f/2.8, also manual focus. I dial in focus on a distant object in the daylight, then use some electrical tape on the lens to hold the focus ring in place.

That’s never worked for me. I always bump it where the electrical tape didn’t hold. I usually just live view the moon or some brighter star in 5x mode and then switch to MF and recheck every so often.

Sounds like you are looking the Sharp Star. I heard they are more for longer lenses rather than wider ones. It is basically a bhatinov mask commonly used on telescopes, which are longer focal length. Is it worth getting?

TRhoads wrote in post #18539706I do have the SharpStar and find it works great for wide angle too...

Thanks, I'll have to look into again.

Really nice shot......if I may be a bit nosey? was this stacked or just PP? You use the 24-70 ? I try to shoot MW as I travel as I home in a urban area....... again, very nice work! ( your composition makes it to me!)

I like the composition for sure. I also wonder about how many images were used etc.

On another note, your profile mentions you are from Central CA, where about?

I live in Salinas and always looking to get out with some local people to shoot. Couple friends and I get out occasionally and I am trying to plan a night shot in late Sep. Perhaps you might want to join?

This was actually taken just east of Pinnacles National Park...then I drove home throughSalinas. I live in Visalia but I am always out & about in Central Cali. We could for sure plan a meet up. Just PM me.

Life is hard...but I just take it one photograph at a time. 5DMK47DMK2Canon Lenses: 50/1.4, 135/2.0, 100-400mm II, 24-70/2.8 II

This was two shots.....the foreground I took a little earlier in the evening while the moonlight was available. The sky was later at night & I had to darken it a bit to bring out the MW. Rarely do I do a composite so this was fun for me.

I went out on Saturday night to shoot the milky way and wanted to try the smooth reflection app for the foreground and blend a single sky shot in. Went to bed early and the sky was crystal clear and unreal. Milky Way core was rising at around 2am so got up and went to the beach for this shot. Unfortunately the cloud had started to come in (was supposed to be crystal clear all night) I managed to get one shot with a little bit of the milky way showing and then shot my SR foreground to blend in.I stuck it out for an hour and then I couldn't see a single star for the cloud so went home. I will definately try this again for a clean foreground shot.

Nice shot, so do you use the app for noise reduction or for long exposure simulation? I think you mentioned the beach so I'm assuming the latter. Does the app do nose reduction similar to median stacking in PS?

You said you got 16 shots but also say you will try again for a clean foreground? I'm just trying to see if I should use the app, I already have it, but do stacking in PS. Thanks
